{MPROVEMENT IN CANS 'FOR OILS.

Specication forming part of Letters Patent No. 141,615, dated August 5,1873 application iiled J une 27, 1873.

To all whom it may concern:

Be it known that I, F. CORTEZ WILSON, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inOil-Tanks, and I do hereby declare the following to be a full and exactdescription of the same, reference being had to the accompanyingdrawings forming part of this specification, in which- Figure l is aperspective view, showing the dome opened; Fig. 2, a section, showingthe dome closed 5 Fig. 3, a section, showing a modilication of thesliding portion of the dome 5 and Fig. et, a section, showing the samearrangement applied to a cover fitting into or over the top of the tank.

Similar letters of reference in the accompanying drawings denote thesame parts.

This invention, which is an improvement on the patent of W. C.Strickler, N o. 130,762, dated August 20, 1872, relates to circularoiltanks, having conical domes or tops, one-half of the top beingadapted to slide around the tank in order'to provide means of access tothe interior 5 and it has for its object to improve the construction ofthe upper portion of the tank and the connection of the tank and dome,or tank-cover and dome combined. To this end the invention consistsmainly in a vertical guard or ange around the upper edge of the body ofthe tank, said guard being formed by soldering the conical top or dometo the inside of the tank or tank-cover about half an inch below itsedge, and constituting a guard which keeps the sliding portion of I thedome in place or serves as a track or guide for the latter, as I willnow proceed to describe.

In the drawings, A represents the tank, B the stationary part of thedome, and C the sliding part, each composing about onehalf of the dome.The stationary part B is soldered to the inside of the tank or tankcoverabout half an inch below its upper edge D. The'latter consequentlyprojects above, and forms a guard around the edge of the dome. The loweredge of the sliding cover C rests against the inner side of the edge D,while its upper edge and that of the stationary part B is held-between acollar, E, at the apex of the dome, and a beveled washer, F, screwedthereto, the same screw entering the wooden knob G and holding it inplace. H represents a narrow inclined flange extending around the innerside of the tank on the side opposite the part B of the dome, and on thesame level as the lower edge thereof, said ange constituting, inconnection with the part B and projecting edge D, a narrow grooveextending entirely around the tank, the part C sliding in said groove.

A modification of this arrangement is shown in Fig. 3, in which thelower edge of the sliding part C is provided with a groove, I, to fitover the edge D, the latter being suitably wired for the double purposeof strengthening it, and forming a suitable track for the part G toslide on. By this means the ilange BI is dispensed with.

If desired, friction-rollers may be placed in the groove I inlarge-sized tanks, to make the y working of the cover more easy.

By this construction, the appearance of the tank is improved, and theoperation of the sliding cover is rendered much easier than heretofore.

The sliding door may be made in two pieces, if preferred, arranged toslide to the right and left, respectively.

The above-described improvements may be, with equal advantage, attachedto a cover composed of a narrow rim, the false topor diaphragm, and thedome.

Having thus described my invention, what I claim as new isl. In anoil-tank having a conical top or dome, a vertical guard or track aroundthe upper edge of the body or cover, to receive the sliding portion ofthe top or dome, substantially as described, for the purpose speci fied.
